FEEDING-TABLE FOR ROLLING-MILLS.

SPECIFICATION forming part of Letters Patent No. 348,216, dated August31, 1886.

Application filed April 28, 1886.

To all whom it may concern:

Be it known that 1, ROBERT W. HUNT, of the city of Troy, county ofRensselaer, State of New York, have invented new and useful Improvementsin Feeding-Platforms for R011- ing-Mills, of which the following is aspecifica- My invention relates to that class of apparatus which is usedin connection with rollingmills for manipulating the blooms that arebeing formed into rails, the object of my invention being to accomplishby a mechanical means the transfer from the delivery side of the upperpasses of thetrain a bloom coming therefrom, and to turn it upon itsside when being transferred from one of the upper to one of the lowerpasses to meet the shaping condition of the latter, and also to deliverit to one of the lower passes.

My invention consists (as will be more fully detailed hereinafter inconnection with its illustration and set forth in the claims) in thecombination, with a receiving and delivering platform that is composedof a series of rollers arranged to be opposite the bottom of the lowerpasses of the train and parallel with the latter, and being actuated toturn with their upper surfaces moving toward the train, and only movablein such rotation, of turning studs having curved surfaces and beingprojected upwardly between the rollers of said platform, and a movabletable constructed with a frame and having rollers mounted to turntherein when a bloom is run out thereon, said table being actuated torise and stop opposite the upper passes of the train to receive a bloomor partly-formed rail coming therefrom, and then actuated to descend sothat the rollers of said tableshall alternatingly pass between therollers of the platform to deliver a bloom thereon, theupwardly-projected studs being arranged to pass between the rollers ofboth the platform and table and to so engage with the descending bloomas to turn it upon its side when it is being deposited on the platform,which delivers it to that one of the lower passes of the train to whichthe bloom is opposite.

My invention also consists in the sub-combination of the partsillustrated and described where they perform specific functions, as willbe specified in the claims.

Serial No. 200,414. (No model.)

Accompanying this specification, to form a part of it, there are fourplates of drawings containing four figures illustrating my inven tion,with the same designation of parts by letterneference used in all ofthem.

Of these illustrations Figure 1 is a plan view of the mechanismcontaining my invention and shown as being arranged in front of one ofthe sections of a three-high train, and with the movable tableillustrated as down and with its rollers between those of the platform.Fig. 2 is a front elevation of a section of a train with my inventionshown as applied thereto, and with the movable table shown as down and alittle below the platform. Fig. 3 shows the train-rolls in verticalsection and the movable table and platform in side elevation, the tablebeing illustrated as down opposite the lower passes of that part of thetrain represented. Fig. 4 also shows the rolls of the train in verticalsection, the movable table and platform in side elevation, but with themovable table illustrated as raised up in a receiving position oppositethe upper passes.

The several parts of the mechanism thus illustrated are designated byletter-reference, and the function of the parts is described as follows:

The letters I-I indicate the housings of that part of the trainrepresented; It, the upper rolls; R the middle rolls, and R the lowerrolls.

The letters U, U U", and U" indicate the upper passes, and P, P, I, andl? the lower passes.

The letters D indicate a platform consisting of a series of rollers, (I,having bearings for their shafts S in the frame F. The shafts of theserollers d are provided with sprocketwheels V, which connect bychain-belts B to receive power, by which they are actuated to rotatewith their upper surfaces turning toward the train. These rollers d arearranged in the frame F, so as to leave the spaces a between them, thepurpose of which spaces will be subsequently described herein.

The letter 1 indicates an idler-roller arranged parallel to the train,with its upper surface in 'a line or nearly in a line with the bottom ofthe upper passes of the train and immediately in front-0f the latter.

The letter 1 indicates another idler-roller the train.

that is arranged to have its upper surface on a line or nearly on a linewith the bottom surface of the lower passes of that part of the trainwhich is illustrated. H 7 N h The letter T designates a movable tablehaving a frame, F, and this table is constru cted with a series ofrollers, 22, having their shaftbearings in said frame. This frame F ismade narrower than the frame F of the platform D, so that the frame ofthe movable table may pass down inside of the frame of the platform,with the rollers of this table so arranged in its frame as to be overthe spaces a, between the rollers d of the platform. Thus constructed,when the movable table descends its rollers pass alternatingl'y betweenthose of the platform D, .with the frame of the movable table resting onthe shafts S of the platform by means of recesses 6, made in the undersurface of the sides of the movable table-frame. This table T is adaptedto be raised by means of the connecting-rod O, the angular turn-leversL, and the pivoted rods J, which connect one arm of each of said leverswith the table, and by the return reciprocation of the connecting-rod Oand the counterpoise M the table is caused to descend. When the table,is raised,it stops at a point which brings the upper surface of itsrollers on a line or nearly on a line with the bottom of the upperpasses, and when the table T is actuated to descend it stops in itsdescent at a point a little below the rollers of the platform D. Whenthe table T is raised, as shown at Fig. 4, a bloom or partly-formed railcoming from an upper pass is run out onto the table by the expellingforce of the rolls, the rollers b. turning to facilitate its receptionthereon, and when the table descends to a point a little below thesurface of the rollers of the platform it is by the latter moved forwardto that one of the lower passes to which the bloom is opposite. f

The letters E, E", and E designate three series of turning and guidestuds that are upwardly projected between the rollers of the platform,and which are also so arranged that when the table descends these studswill project up between the rollers of the latter. The studs of eachseries are arranged to be parallel with each other on a line drawn atright angles to The studs of each series are of an A form, with theirsides having an incline from the upper pass, from whence the bloomcomes, toward the bottom pass, at which the bloom is to be againreturned to the train,one side of the studs serving to turn the bloom inits descent on the: table and the opposite sides of each of the adjacentseries of studs serving as guides for the return of the bloom to therolls. The series of studs E engage with the bloom coming from the upperpass, U, and turn it on its side as it descends on the table T, so thatthe latter will deliver it on the platform D, where it will be oppositethe lower pass, P while the sides 0 of the adjacent series of studs, Eserveas guides, when the series of studs E? serving as guides for the.

bloom when being returned to the train by the rollersof the platform D.The turning and guide studs of the series E engage with thepartly-formed rail or bloom coming from the upper pass, U as it descendson the table T, to turn it upon its side, so as to bring it opposite thelower pass, P", when delivered" upon the rollers of the platform D, thatreturn it to the train.

While I have thus described my invention as applied to rail-trains, itmay be used for handling blooms of any kind requiring a likemanipulation. If desired, the table T and platform D may be operatedclose up to the train, and the idler-rollers I and 1 dispensed with.

As the platform D, made with the spaces a between the rollers thereof,when combined with the table T, actuated to rise and descend, so thatwhen down its rollers are alternatingly' between the rollers of theplatform and a little below them, would perform the same functionconnectedly, whether the bloom or partly-formed rail was turned orguided by.

the studs which I illustrate and describe or some other mechanism; henceI.do not limit my invention of the combined movable table and aplatform,as I show them to be construct ed and arranged to operate totheir combination with the said studs.

I am aware that atable provided with rollers adapted to be raised and todescend so as to be operated in connection with the upper and lowerpasses of a train is not new, broadly considered. l

I am also awarethat a roller-platform provided with studs or guides andarranged opposite the lower passes of a train is shown and described inLetters Patent granted to me February, 10, 1885, No. 311,899.

Having thus described my invention, what I claim, and desire to securebyLetters Patent,
